New Approach to Acquiring Users for Local Currency Ain Pay with NFT Stamp Rally ~Pilot Experiment Connecting Digital and Real-world in Higashimurayama City~

SUSHI TOP MARKETING Inc. (Head Office: Chiyoda-ku, Tokyo; Representative Director CEO: Daisuke Tokunaga; hereinafter "the Company") collaborated with the Higashimurayama Regional Promotion Organization (Location: Higashimurayama City, Tokyo; Representative Director: Takeyu Toma; hereinafter "Higashimurayama Regional Promotion Organization"), which operates the digital local currency "Higashimurayama Ain Pay," to conduct a pilot experiment of an NFT digital stamp rally at the "Ain Pay BIG Marche" held in Higashimurayama City on Saturday, March 7, 2026.

On the day of the event, QR codes were set up at 22 spots, allowing visitors to acquire NFTs (digital stamps) simply by scanning them with their smartphones. Since participation was possible via LINE, people of all generations could join, recording 1,047 NFT distributions and 215 participants in a single day.

Based on the data obtained from this pilot, we will proceed with considering continuous circulation promotion measures in collaboration with Ain Pay.

**Background and Challenges** Higashimurayama Ain Pay is a digital local currency platform within Higashimurayama City, boasting over 31,000 users and 550 participating stores. The Higashimurayama Regional Promotion Organization has a vision of "creating the future of Higashimurayama starting with local currency" and defines the desired state of Ain Pay as follows:

* **Increase users and foster local fans:** Realizing a customer journey of "Know → Try → Continue using → Support local businesses and participating stores → Become a fan." * **Evolution into a "local app":** Beyond just a payment method, it aims to become a local information hub used in all aspects of daily life, such as shopping, administrative procedures, events, and tourism.

To achieve this vision, it was necessary to visualize the behavior of not only Ain Pay users but also non-users and create a mechanism to naturally encourage them to start using it. Through the "Creww Growth" open innovation program operated by Creww, the Company proposed and was adopted for an NFT digital stamp rally as a means to address this challenge.

**Initiative Overview** The Company utilized "Token Graph Marketer," which can consistently handle NFT distribution and analysis, to design and implement an NFT digital stamp rally that both Ain Pay users and non-users could participate in. The "account-less" UX, requiring no app, just QR scanning and LINE completion, enabled participation from a wide range of age groups, including those unfamiliar with digital technology.
